BACKGROUND OF THE INVENTION '1. Field of the Invention I This invention relates generally to reels, and particularly to improvements in cloth-board reels for carrying cloth wound thereabout.

2. Description of the Prior Art My U. S. Pat. No. 3,286,828 discloses a cloth-board reel fabricated entirely of paper stock and extremely staunch, durable and reliable under all conditions of use. Attempts have been made to replace this type of reel with one standard, molded or otherwise formed entirely of plastic material. While such reels may be less expensive to fabricate, they have not proved to be entirely satisfactory because they do not stand up sufficiently well under the abuse they receive in normal use. In particular, they do not have the strength necessary to withstand the torsional and buckling stresses to which they are subjected during machine winding of cloth on the reels; In addition, when clothiswound on a reel, it may not be completely free of moisture. In order to prevent moisture being trapped between the reel and the innermost coil of cloth wound thereabout, the interface therebetween must be vented to atmosphere and/or the moisture must be absorbed by the reel by capillary attraction. Since plastic material is impervious to air and incapable of absorbing moisture by capillary attraction, a reel made entirely of plastic material is not suited for the purpose intended for moisture is trapped at said interface and as a result the cloth may be damaged by the formation of mildew.

Furthermore, it has been found that a fine powder forms on the outer surface of a reel made entirely of plastic material, and that'the powder adheres to the cloth when the cloth is removed from the reel.

SUMMARY OF THE INVENTION A principal object of the invention is to provide a cloth-board reel consisting of a core of plastic material made extremely staunch, durable and reliable under all conditions of use preferably by reason of being tightly wrapped, encased or jacketed in a sheetor sleeve of rather heavy paper stock.

Another object of the invention is to provide such a reel wherein the outer surface areas of the core are fluted so as to place the inner surface areas of the paper stock sheet directly in communication with atmosphere.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. I is a plan view of the preferred cloth-board reel ings. It is not addressed to the scope of the invention, which may be practiced in a variety of forms.

Referring particularly to FIGS. 1-3, a cloth-board reel constructed in accordance with the invention, generally designated 10, comprises a semi-rigid core 12 preferably made of a comparatively inexpensive, light weight polymeric material, such as low density foamed polystyrene, and measuring, for example, 8 inches X 1 inch X l foot-6 inches. The core may be extruded,

molded or otherwise formed of such material, and, is provided with oppositely facing wide, flat sides 14 and 16 rounded longitudinally extending narrow edges 18 and 20, as shown. The side 14 is provided with a series of four longitudinally extending laterally spaced flutes or grooves 22 each extending the full length of the core, and the side 16 is provided with a series of four longitudinally extending laterally spaced flutes or grooves 24, staggered, as shown, relative to the grooves 22, each extending the full length of the core.

The core 12 is tightly wrapped or encased in a sheet 26 of foraminous or perforate paper stock adhesively applied to the core. The sheet 26, of rather heavy paper stock, extends completely around the core to form a butt joint 28, as shown. Only the opposite ends of the core remain exposed. Linedchip paper stock 0.016 of an inch thick and provided all over with perforations or foramina 1 inch on centers and one-eighth inch in diameter, designated 30, has proved tobe' entirely satisfactory for the purpose intended.

A cloth-board reel constructed in accordance with the invention is a unitary structure the core 12 of which is rendered rigid by the paper stock sheet 26. Such a reel is economical to fabricate, light in weight and extremely staunch, durable and reliable under allconditions of use. In addition, air flowing freely through the reel via the flutes 22 and 24 comes into direct contact with the paper stock sheet 26. Thus, moisture drawn by the sheet 26 (by capillary attraction) from the cloth wound thereabout is carried away to atmosphere and the development of mildew is thereby arrested. Some or all of the perforations or foramina 30 may be arranged to register with the flutes 22 and 24. In this event, the outer surface areas of the paper stock sheet 26 are vented to atmosphere through such perforations or foramina 30 and the flutes 22 and 24, and air flowing through the reel via the flutes 22 and 24 comes into direct contact with the cloth wound about the reel, whereby to draw moisture therefrom and thus aid in preventing the formation of mildew. Furthermore, the core 12 is clad in the paper stock sheet 26, as a consequence of which the cloth wound about the reel does not come into direct contact with the core 12. Thus, when the cloth is removed from the reel, it comes off clean, i.e., free of any fine powder shed by the core.

While in accordance with the provisions of the patent statutes, I have illustrated and described the best form of the embodiment of my invention now known to me, it will be apparent to those skilled in the art that changes may be made in the form of the cloth-board reel described without departing. from the spirit and scope of the invention as set forth in the appended claims and that in some cases crrtain features of my invention may be used to advantage without a corresponding use of other features. For example, the flutes 22 and 24 all extend parallel to the longitudinal axis of the cloth-board reel and in a straight line from one end to the other thereof. This feature is not essential. The

desideraturn is at least one flute extending into the reel from one end thereof. The flutes need not extend from one end to the other thereof, and they need not be straight and/or parallel to the longitudinal axis of the cloth-board reel. In fact, one flute spiraling about the core 12 could be adequate for the purpose intended. By way of further example, the entire outer surface of the core 12 could be corrugated by providing it with a series of close adjacent flutes. Still further, by way of example, when it is desired to avoid fluting the core 12, a sheet of perforated or foraminated single face corrugated paper stock may be substituted for the sheet of lined chip paper stock 26, the corrugated face of the sheet being disposed on the inside and being adhesively applied'to the core 12. Moreover, while the core 12 is shown and described as a solid mass of plastic material, it will be understood that the interior thereof may be made hollow and ribs may be provided internally thereof to render the core at least semi-rigid.

Referring particularly to FIGS. 4 and 5, showing modified forms of the cloth-board reel, the core is identical with that of the embodiment of FIGS. 1-3. However, instead of the paper stock being tightly wrapped about the core as shown in FIGS. 1-3, only the substantially wide oppositely facing fluted sides of the core are lined with sheets of paper stock, leaving both longitudinally extending rounded edges and both ends of the core exposed. Referring particularly to FIG. 5, the longitudinally extending edges 54 of the sheets of paper stock, designated 56, are beveled, as shown. The beveled surfaces merge smoothly with the rounded longitudinally extending narrow edges of the core 12; and thus avoid marking of the cloth wound upon the reel.

Referring particularly to FIG. 6, showing still another modified form of the cloth-board reel, the core, designated 58, is identical with that of FIGS. 1-3, except that both substantially wide oppositely facing fluted sides thereof are recessed, as at 60. The recesses are of a depth equal to the thickness of the sheets of paper stock 52, which are respectively received thereby.

What is claimed is:

1. In a cloth-board reel, the combination of A. a core of plastic material having oppositely facing substantially wide sides and rounded-longitudinally extending narrow edges,

B. two sheets of porous paper stock respectively lining said oppositely facing substantially wide sides of the core and leaving only the rounded longitudinally extending narrow edges of the core exposed, said porous paper stock, being adhesively applied to said core whereby to form therewith a unitary structure, and said paper stock being of a weight and thickness sufficient to render said unitary structure rigid, and

C. flute means between said core and paper stock operative to place inner surface areas of said paper stock in communication with atmosphere.

2. The combination according to claim 1 wherein the outer surface of the core is provided with flute means underlying the porous paper stock and extending into the reel from an exposed end thereof.

3. The combination according to claim 1 wherein the outer surface of the core is provided with flute means underlying the porous paper stock and extending into the reel from both exposed ends thereof.

4. The combination according to claim 2 wherein the porous paper stock is foraminated and at least some of the foramina register with the flute means.

5. The combination according to claim 2 wherein the longitudinally extending narrow edges of the sheets of porous paper stock are beveled, and the bevel surfaces merge smoothly with the exposed rounded longitudinally extending narrow edges of the core.

6. The combination according to claim 2 wherein the substantially wide oppositely facing fluted sides of the core are provided with recesses of a depth equal to the thickness of the paper stock, and said recesses respectively receive the pair of porous paper stock sheets.
